Rev. E 101 , 022502 (2020) Identifying if two knots are similar is an open problem that cuts across several disciplines from mathematics to physical sciences; the main challenge is that the knot type is a global property that cannot be determined by looking only locally. In this paper, the authors apply supervised learning techniques to the knot recognition problem in polymers, showing what artificial neural networks can do to address it. EDITORS' SUGGESTION Translational nucleosome positioning: A computational study J. Neipel, G. Brandani, and H. Schiessel Phys. Rev. E 101 , 022405 (2020) How to predict the positions of nucleosomes on DNA is an important problem. The authors show that a simple coarse-grained model of DNA is unable to account for all aspects of the positioning, and they propose a model that assumes the elasticity of DNA changes when it is part of the nucleosome. The new approach shows excellent agreement with previously published experimental work. EDITORS' SUGGESTION Lattice Boltzmann model for weakly compressible flows Praveen Kumar Kolluru, Mohammad Atif, Manjusha Namburi, and Santosh Ansumali Phys. Rev. E 101 , 013309 (2020) The authors propose an energy-conserving multispeed lattice Boltzmann model relevant for acoustic phenomena and weakly compressible flows. By providing simulations of several test cases they demonstrate that the model gives impressive results, including for turbulent flows, even in the presence of objects. EDITORS' SUGGESTION Adsorption anomalies in a two-dimensional model of cluster-forming systems E. Bildanau, J. Pękalski, V. Vikhrenko, and A. Ciach Phys. Rev. E 101 , 012801 (2020) Monte Carlo simulations are used to study a two-dimensional lattice model of particles interacting through short-range attraction and long-range repulsion. Adsorption of particles on a boundary line and the distribution of particle clusters near the boundary were investigated while varying several parameters. The authors find a rich variety of patterns that are qualitatively different from those in liquids with simpler interactions. EDITORS' SUGGESTION Charge oscillations in ionic liquids: A microscopic cluster model Yael Avni, Ram M. Adar, and David Andelman Phys. Rev. E 101 , 010601(R) (2020) The microscopic model of ionic liquids presented in this work reproduces many features previously observed in experiments and simulations. The effective mean-field theory obtained from this model shows that ionic pairs lead to short-range charge oscillations near an interface and that more complex clusters can lead to long-ranged oscillations.
